NOTE:
Address:
A line over a signal name indicates an active low signal. For example,
RESET is active high and RESET is active low. Any reference to voltage,
current, or frequency specified in this document will refer to the nominal
values. The exact values and their tolerance or limits are specified in
Section 13. Electrical
These options are programmable in the mask option registers:
These options are programmable in the option register (see
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
